On the Web: Ka-pow! Superhero short films get kids thinking about climate change

The Green Ninja may sound like a spin-off of the “Power Rangers,” the live-action children’s television series featuring color-coded superheroes. But there’s a little less punch and a lot more thought going into this YouTube science show for kids.

Parasites spread across the Arctic under the 'new normal'

The last several decades have seen Arctic sea-ice minimums drop by more than half in sea-ice area and more than three-quarters in volume. With current models expecting further reductions, scientists are calling it the “new normal” and are trying to grasp its implications — one of which is the occurrence of pathogens never before seen in the Arctic.

Books: A changing literary climate

Climate fiction, or cli-fi, is a new literary genre. Using climate science as a launching pad, these books, films, poetry and other media imagine life on a planet altered by human activity. The genre is still a niche but becoming more common as climate change has captured popular attention.

Subarctic lakes belch more methane on brighter days

Each summer, frozen ground in Arctic and subarctic regions, called permafrost, thaws and releases accumulated methane. For years, scientists have searched for a clear-cut way to estimate the amount of this potent greenhouse gas that these areas contribute to the atmosphere and the changing climate. Now, they have come one step closer to solving part of the problem.

Geomedia: California’s climatic catastrophes detailed in “The West Without Water”

The 2013-2014 California drought has impacted everything from wildfires to food prices across the country. Politicians and the media called this the worst drought in California history, but scientists know that intense multiyear droughts are a regular feature of California’s climate. Fortunately, B. Lynn Ingram and Frances Malamud-Roam have put drought into context for everyone in their new history of California’s droughts and floods, “The West Without Water.”

Scientists go to extremes to monitor Arctic permafrost loss

Researchers are studying coastal erosion in the Arctic — where sea-ice extent has recently reached record lows, permafrost soils are rapidly thawing and the coast is retreating at an astonishing rate of 15 meters per year, more than double the rate of several decades ago.

Humans are influencing some extreme weather events, but not all

In 2012, the world experienced dozens of extreme weather events, including droughts, heat waves, cold spells, extreme rainfalls, big storms like Superstorm Sandy, and a record-low Arctic sea-ice extent. Teasing apart the factors that create extreme weather is a challenge for scientists, especially when it comes to determining whether human-induced climate change plays a role. Recently, 18 different research teams — comprising 80 scientists — took on that challenge.

Climate, terroir, and wine: What matters most in producing a great wine?

Weather and climate have played decisive roles throughout human existence — where and how cultures developed, where they migrated and even how some died out. The most successful early civilizations were those that developed strong agrarian systems based on what crops were most compatible with the climate. If conditions changed for one reason or another, people migrated to areas with a more suitable environment to grow a certain crop or raise specific animals.

Travels in geology: Antarctica: Following in the footsteps of giants

In fall 2012, when I told friends and colleagues that I was heading south for a few weeks, they assumed that I, like many other northeasterners, was going to Florida or the Bahamas for a break from winter weather. Instead, I was headed to the iciest and southernmost place on Earth: Antarctica.

World War G: Zombies, energy and the geosciences

In lieu of doing a "year in review" issue this year, EARTH asked our staff and some frequent contributors to write a short commentary on something that grabbed their attention in 2013. We gave everyone carte blanche. What follows is a collection of extremely varied, often very personal insights into how the planet impacted each individual. In this commentary, EARTH contributing editor Michael Webber draws parallels between zombies and the geosciences.
